(Chalk - 2005)
Starting from the West end of the Bay, the Upper Chalk of Culver Cliff yields excellent sponges such as Porosphaera. Echinoids such as the small Echinocorys subconicula and Belemnites of Belemnitella mucronata can be seen from the Portsdown Member. This is the top of the succession so it is best to search the rocks that have fallen from this thin marl bed. Occasional fish remains can also be found.
(Reading Formation - 2005)
Past the chalk, the Reading Formation can be seen although much of it has been slipped and is covered by vegetation. This bed is mostly unfossiliferious, although a few silicified Echinoids and a few derived microfossils from the chalk have been found.
(London Clay - 2005)
The London Clay and London Clay Basement Bed, immedialy after the Reading Formation is where most of the more interesting fossils can be found. Shark Teeth, worm tubes (Ditrupa) and a range of shells can be found. The London Clay Formation includes the Bagshot Sands which are unfossiliferious. Most of the fossils can be found from the first part of the sequence.
(Bracklesham Group- 2005)
Many various molluscs can be found from the Bracklesham Group, these include; Nummulites laevigatus, Turritella and Venericor planicosta. These are from the Earnley Sand.
(Barton Group - 2005)
The Barton Group is mostly covered up with a sea defence, although during scouring conditions this is exposed on the foreshore. Here, shells of Nummulites prestwichianus and Nummulites rectus can be found. The Becton Sand follows this (Again mostly covered up by defences).
(Headon Hill Formation- 2005)
The Headon Hill Formation which has been badly landsliped can yield a wide range of marine shells. Viviparus, Galba, Planorbina, Potamomya, Melanopsis, Theodoxus, Ostera, Psammotaea, Pelcora, Corbula as well as many other species.
(Bembridge Limestone and Bembridge Marls - 2005)
Lastly at the Eastern end of the bay, the Bembridge Limestone yields superb specimens of Planorbina and Galba.
